DCMT11T304 NS9530 indexable insert for turning — uncoated cermet, 0.4 mm radius | Tungaloy

The DCMT11T304 NS9530 indexable insert is a finishing-grade turning insert engineered for external and internal turning of steel, offering a sharp cutting edge and low cutting forces for small depths of cut.

• Finishing grade for steel accuracy
• Sharp cutting edge for high surface finish
• ISO-compatible 11 size rhombic insert

Precise finishing and consistent surface quality

The combination of the NS9530 uncoated cermet grade and a 0.4 mm nose radius provides a measurable advantage when fine surface quality is required. The sharp cutting edge reduces ploughing and diminishes cutting forces, which is particularly beneficial in continuous-turning applications and when small depths of cut are used. As a result, cycle times remain predictable and downstream polishing or rework is minimised, supporting efficient production flow and improved part conformity.

Secure fit and predictable mounting in ISO systems

Compatibility with toolholders is governed by form, relief angle, tolerance class, fastening method, size and thickness; this insert’s rhombic geometry, 55° cutting angle and 7° relief angle ensure a standardised seating in ISO turning holders. The insert’s cylindrical hole with a one-sided countersink (40°–60°) and the nominal thickness of 3.97 mm contribute to reliable clamping and repeatable positioning, reducing set-up variability and enabling stable cutting conditions across multiple tool changes.

Controlled chip formation for continuous cuts

This grade is optimised for steel and paired with a one-sided chipbreaker designed for continuous chip evacuation in finishing passes. The combination of insert geometry and chip control promotes a predictable chip flow that protects the workpiece surface and the cutting edge, lowering the likelihood of built-up edge and minimising scrap. Where machining stability is limited, selecting the appropriate chipbreaker and cutting parameters preserves tool life and maintains consistent dimensional accuracy.

Practical benefits for machining productivity

Using a finishing insert made of carbide with a cermet composition improves wear resistance at moderate cutting speeds while preserving a fine edge for superior finishes. The standard ISO designation facilitates straightforward stock management and compatibility with many common holders, which supports quick replacement and minimal machine downtime. For shops seeking reproducible finishes and shorter post-process work, this insert represents a pragmatic balance between surface quality and process reliability. Metav Werkzeuge can supply recommended cutting parameters and batch availability to aid process integration.

FAQ

Which materials is this insert best suited to machine?
The DCMT11T304 NS9530 Tungaloy indexable insert is a finishing grade optimised for machining steel, offering low cutting forces and high surface quality in continuous cutting conditions.

Is the NS9530 grade coated or uncoated?
The NS9530 grade is an uncoated cermet, designed to maintain a sharp cutting edge for fine finishing work.

What holder characteristics are required for correct fitment?
Compatibility depends on matching the insert form, 55° geometry, 7° relief angle, tolerance class, fastening method and nominal thickness; ISO turning holders sized for 11 are suitable when these parameters align.

What are the nose radius and thickness of the insert?
The insert has a 0.4 mm nose radius and a thickness of 3.97 mm, suitable for small depths of cut and finishing passes.

How does the chipbreaker affect performance?
The one-sided chipbreaker encourages controlled chip flow during continuous turning, supporting consistent surface finish and reducing the risk of built-up edge.
